Benidipine is a calcium channel blocker that is used to treat hypertension. However, during the manufacturing process, impurities may be introduced that can affect the efficacy and safety of the drug. These impurities can include related compounds, degradation products, and residual solvents. Regulatory agencies require strict limits on the levels of these impurities in the final drug product to ensure patient safety. Analytical methods are used to identify and quantify these impurities, and manufacturers must implement strategies to control their formation and minimize their presence.
